Animated gifs cause some browsers problems. IE tends to puke on them more often than Firefox or Chrome, but it's not exclusive to IE. At this point, I'm unaware of a solution. Most of the time, we either live with it or ask a moderator to make the gif go away.

— Sorry. No pearls of wisdom in this oyster.
